6 Claims.

My invention raltes to fliers of the type used with spinning machines,and more particularly to a flier block arrangement having improved meansfor attaching and supporting the flier wires.

The present application, which is a division of my application SerialNo. 103,517, filed July 7, 1949, now PatentNo. 2,577,346, issuedDecember 4, .1951, relates to a flier block and flier wire supportwherein the support is detachably secured to the flier block by means ofthe cooperative engagement between a plurality of lugs formed on theblock, and complementary recesses formed in. the flier wire support.

In Patent 2,187,862, issued to me January 23, 1940, there is disclosed aflier construction hav-- ing a flier wire support member in the form ofa plate adapted to fit over the head portion of the flier body or block,the plate being attached to the flier body by means of a cap positionedbelow the plate and attached thereto by spot welding; also in Patent2,212,299 issued to me August 20, 1940, there is disclosed a flierconstruction for a bi-partite flier wire support member in the form ofcomplementary sections having semi-circular cut-out portions adapted toseat in a peripheral groove at opposite sides of the flier block. Thearms, defined by the cutout portions, are adapted to overlap and meansare provided for engagement with the peripheral flanges of the blockwhereby the sections of the flier wire support are securely clamped orlocked to the flier block.

I have found, after considerable research and experimentation, that theconstructions of my prior patents can be substantially simplified toprovide improved operation with marked economies in manufacture, andthat improved results can be obtained by reason of certain modificationsand/or combinations of the arrangements of the aforementioned patents.

An object of my invention is to provide a flier block having improvedmeans for attaching and supporting the flier wire thereon.

Another object of my invention is to provide a flier construction havingmeans whereby the arms of the flier wires are supported in a fixed planein the vicinity of their points of attachment to the flier block.

Yet another object of my invention "is to provide an'improved flierconstruction wherein the flier wires are attached to the flier block bycrossing or overlapping the wires in the vicinity of the body portion ofthe block whereby the arms of the flier wires are maintained in thedesired seated position on the block.

Still another object of my invention is to provide an improved flierwire support having means associated therewith adapted for engagementwith the body of the block whereby 2 relative movement of the supportwith respect to the body of the flier is prevented.

"With these and other objects in view, which may be incident to myimprovements, the invention consists in the parts and combinations to behereinafter set forth and claimed, with the understanding that theseveral necessary elements, comprising my invention, maybe varied inconstruction, proportions and arrangement, without departing from thespirit and scope of the appended claims.

In order 'to make my invention more clearly understood, I have shown inthe accompanying drawings means for carrying the same intopracticaleffect, without limiting the improvements in theiruseful applications tothe particular constructions, which for the purpose of explanation, havebeen made the subject of "illustration.

In the drawings:

Figure 1 is an elevational view, partly in .section, showing my improvedflier in operative position on a bobbin spindle.

Fig. 2 is a top'plan view of the flier wire port used with the fliershown in Fig. 1.

Fig. 3 is a top ,plan view, showing a flier wire support in operativeposition on the flier block.

"Fig. 4is a bottom plan view of the flier shown in Fig.1; and

Fig. 5 is a perspective view of the flier block used with'the fliershown in Fig. 1.

The proposed form of "flier construction of the present invention,comprises essentially, a flier block in the form of a centrally,apertured body member ,having base and .head portions, a peripheralflier wire support member ,formed on the body of the block between thebase and head portions, and a fflier .wire support adapted to seat onthe peripheral support. The :flier Wire support member, which .may beformed from metal or other suitable material, isprovided with a centralopening adapted to receive the head portion of the block, and is alsoprovided with a plurality of .cut-out portions contiguous to the centralopening, designed to receive complementarylug members formed on the headportion. In assembling the flier, the flier wire :support is placed onthe head of the block. with the lug members extending through.thecut-out portions, .and thereafterwards upon relative rotationalmovement between the block-and the-support, the .flier who support issecurely clamped to 'theblock. l

Referring to the drawings, and more particularly toFig. 1, there isshowna flier arrangement associated with aibobbin I, mounted inoperative position on a suitable spindle2, of a conventional windingmachine. The bobbin is provided with a head member 3, and a centrallyrecessed por tion 4 adapted to receive a ferrule 5 having .an aperture 6through which the flier .foot 1 is insup f Serted in the flier block,designated generally by numeral 8, comprising a centrally apertured bodyportion 9 arid ahead portion I0. Between the base and the head portions,there is provided a peripheral flange II adapted to form a seat for theflier wire support member, as will be explained more fully hereinafter.

Referring to Fig. 2, the flier wire support, designated generally bynumeral I2, is of general rectangular shape and as here shown, is formedfrom metal. It will be understood that the support may be formed fromother materials having the necessary rigidity and adapted for cuttingand/or forming. The support is provided with a central opening adaptedto receive the head II] of the flier block, and the body portion isformed with a plurality of cut-out portions I3, designed to receivecomplementary lugs I4, formed on the head of the flier block, as will bedescribed more fully hereinafter. In order to maintain the arms of theflier wires in desired separated position, the support is provided withdiagonally arranged grooves I at opposite ends thereof and depressedportions I6 between adjacent grooves.

As will be seen in Fig. 4, the free ends I! of the support I2 areslotted as at I8, and are turned backwardly and inwardly upon themselvesto form flier wire attaching means. Each of the flier wires comprises acentral block engaging portion I9, having arms 2.1, extending outwardlytherefrom. It will be noted that the wires are crossed or overlapped asat 2I, and that arms are urged into seated position in slots I8 byreason of the tension to which they are subjected when the wires arearranged, as shown, in operative position with reference to the blockand its associated flier wire support. The arms of the flier wires, asheretofore noted, are maintained in desired separated position by meansof the depressed portions I6 and grooves I5. Portions of the arms in thevicinity of the ends of the support seat in the grooves I5, formed bypressing the material of the support outwardly above the plane of itsbody portion, and the intermediate portions are separated by the stopsI6, formed by pressing the material of the support downwardly below theplane of the body portion of the support.

The flier block (Fig. 5) designed for use with the support I2, comprisesa centrally apertured body 9, having a head portion Ill, and an oiT-setfoot I adapted for insertion through aperture 6 formed in the ferrule 5of the bobbin I. The head portion of the block is provided with aplurality of spaced lugs or projections I4, and

between the base and head portions, the block is formed with a pair ofstepped peripheral flanges I I and 22, providing supports for the flierwire support member and the flier wires, respectively.

The flier is assembled by inserting the head portion In of the flierblock through the central opening of the support I2, with lugs I4coinciding with the cut-out portions I3, Thereafterwards, the block isrotated to bring the lugs to positions intermediate the cut-outportions, thus locking the flier wire support and the flier blocktogether. The design of the lugs, cut-out portions and the width of thegroove between the lower faces of the lugs and the upper face of flangeI I, are correlated with respect to the flier wire support whereby asnug frictional fit is attained to securely, lock the parts together,after they are assembled.

" In connection with the assembly of the flier,

and more particularly the assembly of the flier wire support and theflier block, Fig. 2, which is a top plan view, shows the relativeposition of the parts after the head I0 of the block has been insertedin the central opening of the support. and prior to rotation of theblock or the support to lock the parts together. In the position shown,it will be seen that the lugs I l are in the cut-out portions I3, whichportions terminate in arcuate shaped ends 23 at greater radial distancesfrom the center of the support than the peripheral portions 24 of thecentral opening in the support. The relative positions of the parts,after rotation of the block or the support, is shown in Fig. 3. It willbe seen that the lugs I4 now extend over arcuate portions 24 and, asindicated hereinabove, by reason of the design of the lugs, cut-outportions and the width of the groove between the lower faces of the lugsand flange I I. a snug frictional fit is obtained.

While I have shown and described the preferred embodiment of myinvention, I wish it to be understood that I do not confine myself tothe precise details of construction herein set forth by way ofillustration, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing irom thespirit of the invention or ex- A ceeiin the scope of the appendedclaims.
